胃大部切除术后，残胃炎的发生率很高，可高达60％～100％，已有的研究表明，残胃粘膜的不典型增生可达94％，术后10年以上的患者，其中药13．3％可并发残胃癌，故残胃炎是引发胃癌的因素之一。临床上中西药治疗残胃炎正在不断探讨中，有个案和临床经验报导，但尚缺乏规范系统的临床实验研究．残胃炎作为一种癌前期病变，探讨其有效的防治措施，具有十分重要的临床意义。 Subtotal gastrectomy, the high incidence of residual gastritis, up to 60% to 100%, the existing studies have shown that atypical hyperplasia of gastric mucosa up to 94%, after 10 years of patients, of which Drug 13.3% can be complicated with residual gastric cancer, so the residual gastritis is one of the factors that cause gastric cancer. Clinic clinical treatment of residual gastritis is under continuous investigation, there are cases and clinical experience, but the lack of normative systematic clinical experimental studies. As a precancerous lesion, the study on the effective prevention and treatment of residual gastritis has very important clinical significance.
